The term 'PERSON ACTING FOR ANOTHER' can be summarized as a PROXY, which is a five-letter word. A PROXY is a person who is authorized to act on behalf of another person or entity. This type of arrangement is often used in business and legal contexts, where one person is given the authority to make decisions or take action on behalf of another. In some cases, a PROXY may be appointed to represent a shareholder in a company's board of directors. In other cases, a PROXY may be appointed to vote on behalf of a voter in an election.
